Remove a lot of obsoleted options

These options were ancient or made obsolete a long time ago, it is
safe to remove them.

Also stop printing ancient options, they should be treated the same as
unknown options.

Removed options: lwres, geoip-use-ecs, sit-secret, use-ixfr,
acache-cleaning-interval, acache-enable, additional-from-auth,
additional-from-cache, allow-v6-synthesis, dnssec-enable,
max-acache-size, nosit-udp-size, queryport-pool-ports,
queryport-pool-updateinterval, request-sit, use-queryport-pool, and
support-ixfr.
